Ma ka hopena o Mei ua mālama ʻia kahi hālāwai pūnaewele ma ke kumuhana . Ua kamaʻilio mākou e pili ana i nā ipu, Kubernetes a me ka orchestration ma ke kumu, nā pae hoʻohālike no ke koho ʻana i nā ʻoihana a me nā mea hou aku. Ua kaʻana like nā mea komo i nā hihia mai kā lākou hana ponoʻī.
Nā mea komo:
- Evgeniy Potapov, Luna Nui o ITSumma. ʻOi aku ma mua o ka hapalua o kāna mau mea kūʻai aku ke neʻe nei a makemake paha e hoʻololi iā Kubernetes.
- ʻO Dmitry Stolyarov, CTO "Flant". Loaʻa iā 10+ mau makahiki o ka ʻike hana me nā ʻōnaehana pahu.
- ʻO Denis Remchukov (aka Eric Oldmann), COO argotech.io, ex-RAO UES. Ua hoʻohiki ʻo ia e kamaʻilio e pili ana i nā hihia i ka ʻoihana "koko".
- Andrey Fedorovsky, CTO "News360.com"Ma hope o ke kūʻai ʻana i ka hui e kahi mea pāʻani ʻē aʻe, ʻo ia ke kuleana no ka nui o nā papahana ML a me AI.
- ʻO Ivan Kruglov, ʻenekinia ʻōnaehana, ex-Booking.com.ʻO ia ka mea i hana nui me Kubernetes me kona mau lima ponoʻī.
Nā Kumuhana:
- ʻO ka ʻike o ka poʻe e pili ana i nā ipu a me ka hoʻokani pila (Docker, Kubernetes, etc.); ka mea i ho'āʻoʻia ma ka hana a iʻole i kālailaiʻia.
- Ka hihia: Ke kūkulu nei ka hui i kahi hoʻolālā hoʻomohala ʻoihana no nā makahiki. Pehea ka hoʻoholo ʻana inā e kūkulu (a neʻe paha i ka ʻōnaehana o kēia manawa) i nā ipu a me Kuber a i ʻole?
- ʻO nā pilikia i loko o ka honua ʻōiwi, he aha ka mea i nalowale, e noʻonoʻo kākou i ka mea e hiki mai ana i ka lā ʻapōpō.
Ua hiki mai kahi kūkākūkā hoihoi, ʻokoʻa nā manaʻo o ka poʻe komo a ua nui nā manaʻo i makemake wau e kaʻana like iā ʻoe. ʻAi , a ma lalo iho kahi hōʻuluʻulu o ke kūkākūkā.
He kūʻai maʻamau a maikaʻi paha ʻo Kubernetes?
"Ua hele mākou i laila (Kubernetes. - Ed.) i ka wā ʻaʻole i ʻike kekahi. Hele mākou iā ia inā ʻaʻole ʻo ia ma laila. Ua makemake mākou ma mua" - ʻO Dmitry Stolyarov
Kiʻi mai Reddit.com
ʻO 5-10 mau makahiki i hala aku nei he nui nā mea hana, a ʻaʻohe maʻamau hoʻokahi. I kēlā me kēia ʻeono mahina, puka mai kekahi huahana hou, a ʻoi aku paha ma mua o hoʻokahi. ʻO Vagrant mua, a laila Paʻakai, Chef, Puppet, ... "a kūkulu hou ʻoe i kāu ʻoihana i kēlā me kēia ʻeono mahina. Loaʻa iā ʻoe ʻelima mau luna hoʻokele e hana mau nei i ke kākau hou ʻana i nā configs, "hoʻomanaʻo ʻo Andrey Fedorovsky. Manaʻo ʻo ia ʻo Docker a me Kubernetes i "hoʻonui" i ke koena. Ua lilo ʻo Docker i mea maʻamau i nā makahiki ʻelima i hala, ʻo Kubernetes i nā makahiki ʻelua i hala. A maikaʻi kēlā no ka ʻoihana..
Ua aloha ʻo Dmitry Stolyarov a me kāna hui iā Kuber. Makemake lākou i kahi mea hana ma mua o ka puka ʻana mai, a hiki i laila ke ʻike ʻole kekahi. I kēia manawa, no ka maʻalahi, ʻaʻole lākou e lawe i kahi mea kūʻai aku inā maopopo lākou ʻaʻole lākou e hoʻokō i nā Kubernetes me ia. Ma ka manawa like, e like me Dmitry, "he nui nā moʻolelo kūleʻa nui e pili ana i ka hana hou ʻana i ka hoʻoilina weliweli."
ʻAʻole ʻo Kubernetes wale nō ka hoʻoponopono ipu, ʻo ia kahi ʻōnaehana hoʻonohonoho hoʻonohonoho me kahi API i kūkulu ʻia, kahi ʻāpana pūnaewele, L3 balancing a me nā mea hoʻokele Ingress, kahi e maʻalahi ai ka mālama ʻana i nā kumuwaiwai, scale a abstract mai nā papa haʻahaʻa o ka ʻōnaehana.
ʻO ka mea pōʻino, i ko mākou ola pono mākou e uku no nā mea āpau. A he nui kēia ʻauhau, ʻoiai inā mākou e kamaʻilio e pili ana i ka hoʻololi ʻana i Kubernetes o kahi hui me kahi ʻoihana hoʻomohala, e like me ka manaʻo o Ivan Kruglov. Hiki iā ia ke hana kūʻokoʻa i loko o kahi hui me kahi ʻōnaehana kuʻuna a me Kuber. ʻO ka mea nui e hoʻomaopopo i nā ʻano o ka ʻoihana a me ka mākeke. Akā, no ka laʻana, no Evgeny Potapov, nāna e hoʻokaʻawale i nā Kubernetes i kekahi mea hana orchestration ipu, ʻaʻole kū mai kēlā nīnau.
Ua kiʻi ʻo Evgeniy i kahi hoʻohālikelike me ke kūlana i ka makahiki 1990, i ka wā i ʻike ʻia ai ka hoʻonohonoho ʻana i nā mea e like me ke ʻano o ka hoʻonohonoho ʻana i nā noi paʻakikī. I kēlā manawa, hoʻomau ka hoʻopaʻapaʻa a ʻike ʻia nā mea hana hou e kākoʻo iā OOP. A laila ua puka mai nā microservices ma ke ʻano he ala e neʻe aku ai mai ka manaʻo monolithic. ʻO kēia ka mea i alakaʻi i ka puka ʻana o nā ipu a me nā mea hana hoʻokele ipu. "Ke manaʻo nei au e hiki koke mai ana mākou i kahi manawa ʻaʻohe nīnau e pili ana inā pono ke kākau ʻana i kahi noi microservice liʻiliʻi, e kākau ʻia ʻo ia ma ke ʻano he microservice ma ke ʻano maʻamau," manaʻoʻiʻo ʻo ia. Pēlā nō, e lilo ʻo Docker a me Kubernetes i ka hopena maʻamau me ka ʻole o ke koho.
ʻO ka pilikia o nā ʻikepili i stateless

I kēia mau lā, nui nā ʻike no ka holo ʻana i nā waihona ma Kubernetes. ʻOiai pehea e hoʻokaʻawale ai i ka ʻāpana e hana me ka disk I/O mai, conditionally, ka ʻāpana noi o ka waihona. Hiki paha i nā ʻikepili i ka wā e hiki mai ana e hoʻololi nui ʻia e hāʻawi ʻia i loko o kahi pahu, kahi e hoʻonohonoho ʻia ai kekahi ʻāpana ma o Docker a me Kubernetes, a ma kahi ʻāpana ʻē aʻe o ka ʻōnaehana, ma o nā polokalamu ʻokoʻa, e hāʻawi ʻia ka ʻāpana mālama. ? E loli paha nā kumu ma ke ʻano he huahana?
Ua like kēia wehewehe ʻana me ka hoʻokele queue, akā ʻoi aku ka kiʻekiʻe o nā koi no ka hilinaʻi a me ka hoʻonohonoho ʻana o ka ʻike ma nā waihona kuʻuna, ʻo Andrey i manaʻoʻiʻo. Aia ka lākiō o ka cache ma nā waihona maʻamau ma 99%. Inā iho ka mea hana, hoʻomaka kahi mea hou, a "hoʻomaʻamaʻa" ka cache mai ka ʻōpala. A hiki i ka wā e hoʻomehana ʻia ai ka cache, hana mālie ka mea hana, ʻo ia hoʻi ʻaʻole hiki ke hoʻouka ʻia me ka ukana mea hoʻohana. ʻOiai ʻaʻohe ukana mea hoʻohana, ʻaʻole mahana ka cache. He pōʻai ʻino.
ʻAʻole ʻae ʻo Dmitry - ʻo ka hui a me ka sharding e hoʻonā i ka pilikia. Akā ke koi nei ʻo Andrey ʻaʻole kūpono ka hopena no nā mea āpau. I kekahi mau kūlana, kūpono ke kōrum, akā hoʻokomo i ka ukana hou ma ka pūnaewele. ʻAʻole kūpono kahi waihona NoSQL i nā hihia āpau.
Ua māhele ʻia nā hui hui i ʻelua mau kahua hoʻomoana.
Ke hoʻopaʻapaʻa nei ʻo Denis lāua ʻo Andrey ʻaʻole hiki ke hana i nā mea a pau i kākau ʻia i ka disk - nā ʻikepili a me nā mea ʻē aʻe - hiki ke hana i loko o ka kaiaola Kuber o kēia manawa. ʻAʻole hiki ke mālama i ka pono a me ke kūlike o ka ʻikepili hana ma Kubernetes. He hiʻohiʻona kumu kēia. Pane: ʻōnaehana hybrid.
ʻO nā ʻikepili ʻikepili ʻōiwi like ʻole e like me MongoDB a me Cassandra, a i ʻole nā pila memo e like me Kafka a i ʻole RabbitMQ, koi i nā hale kūʻai ʻikepili hoʻomau ma waho o Kubernetes.
ʻO nā mea ʻo Evgeniy: "ʻO nā kumu ma Kubera kahi kokoke-Russian, a i ʻole kokoke i ka ʻoihana ʻoihana, e pili ana me ka ʻoiaʻiʻo ʻaʻohe Cloud Adoption ma Rusia." ʻO nā hui liʻiliʻi a liʻiliʻi paha ma ke Komohana he Cloud. ʻOi aku ka maʻalahi o ka ʻikepili Amazon RDS ma mua o ka hana ʻana me Kubernetes iā ʻoe iho. Ma Rūsia hoʻohana lākou iā Kuber "ma ka hale" a hoʻololi i nā kumu i laila ke hoʻāʻo nei lākou e hoʻopau i ka zoo.
ʻAʻole ʻae ʻo Dmitry i ka ʻōlelo ʻaʻole hiki ke mālama ʻia kahi waihona ma Kubernetes: "He ʻokoʻa ke kumu mai ka waihona. A inā ʻoe e pana i kahi waihona relational pilikua, a laila ʻaʻole ma lalo o nā kūlana. Inā ʻoe e pana i kahi mea liʻiliʻi a me ke ao maoli, i mākaukau noʻonoʻo no ke ola semi-ephemeral, e maikaʻi nā mea a pau. Ua ʻōlelo pū ʻo Dmitry ʻaʻole i mākaukau nā mea hoʻokele waihona waihona no Docker a i ʻole Kuber, no laila ke kū nei nā pilikia nui.
ʻO Ivan, ʻo ia hoʻi, ʻoiaʻiʻo ʻoiai inā mākou e wehe i nā manaʻo o ka stateful a stateless, ʻaʻole mākaukau ka kaiaola o nā ʻoihana ʻoihana ma Kubernetes. Me Kuber, paʻakikī ka mālama ʻana i nā koi kānāwai a me nā hoʻoponopono. No ka laʻana, ʻaʻole hiki ke hana i kahi hāʻina hāʻawi ʻike kahi e koi ʻia ai nā hōʻoia koʻikoʻi o ka ʻike kikowaena, a hiki i ka hāmeʻa i hoʻokomo ʻia i loko o nā kikowaena. Ke ulu nei kēia wahi, akā ʻaʻohe hopena i kēia manawa.
ʻAʻole hiki i nā poʻe komo ke ʻae, no laila ʻaʻohe manaʻo e huki ʻia ma kēia ʻāpana. E hāʻawi mākou i ʻelua mau hiʻohiʻona kūpono.
Ka hihia 1. Cybersecurity o kahi "mega-regulator" me nā kumu ma waho o Kubera
I ka hihia o kahi ʻōnaehana cybersecurity i hoʻomohala ʻia, ʻo ka hoʻohana ʻana i nā ipu a me ka orchestration e hiki ai ke pale aku i nā hoʻouka kaua a me nā hoʻopiʻi. No ka laʻana, i loko o hoʻokahi mega-regulator, ua hoʻokō ʻo Denis a me kāna hui i ka hui pū ʻana o kahi orchestrator me kahi lawelawe SIEM i hoʻomaʻamaʻa ʻia e nānā ana i nā lāʻau i ka manawa maoli a hoʻoholo i ke kaʻina o ka hoʻouka ʻana, hacking a i ʻole ka hāʻule.

Ka hihia 2. Ka neʻe hapa ʻana o nā waihona ʻikepili Booking.com i Kubernetes
Ma Booking.com, ʻo MySQL ka waihona nui me ka replication asynchronous - aia kahi haku a me kahi hierarchy holoʻokoʻa o nā kauā. I ka manawa i haʻalele ai ʻo Ivan i ka hui, ua hoʻomaka ʻia kahi papahana e hoʻololi i nā kauā i hiki ke "pana" me kekahi mau pōʻino.
Ma waho aʻe o ka waihona kumu, aia kahi hoʻonohonoho Cassandra me ka orchestration kākau ponoʻī, i kākau ʻia ma mua o ke komo ʻana o Kuber i ka mainstream. ʻAʻohe pilikia ma kēia ʻano, akā hoʻomau ia ma nā SSD kūloko. ʻAʻole hoʻohana ʻia ka mālama mamao, ʻoiai i loko o ka kikowaena data like, no ka pilikia o ka latency kiʻekiʻe.
ʻO ke kolu o ka papa ʻikepili ʻo ia ka lawelawe hulina Booking.com, kahi o kēlā me kēia node lawelawe he waihona. ʻAʻole hiki i ka hoʻāʻo ʻana e hoʻololi i ka lawelawe ʻimi iā Kuber, no ka mea, ʻo kēlā me kēia node he 60-80 GB o ka mālama kūloko, he mea paʻakikī ke "hoʻokiʻekiʻe" a "hoʻomehana".
ʻO ka hopena, ʻaʻole i hoʻoneʻe ʻia ka ʻenekini huli iā Kubernetes, a ʻaʻole manaʻo ʻo Ivan e loaʻa ana nā hoʻāʻo hou i ka wā e hiki mai ana. Ua hoʻoili ʻia ka waihona MySQL i ka hapalua: ʻo nā Kauā wale nō, ʻaʻole makaʻu e "pana". Ua noho maikaʻi ʻo Cassandra.

E ʻōlelo mākou he hui hou mākou, a i ʻole he hui kahi i kūkulu ʻia ai kahi ʻāpana o ka ʻoihana ma ke ala kahiko. Hoʻokumu ʻo ia i kahi hoʻolālā hoʻomohala ʻoihana no nā makahiki. Pehea ka hoʻoholo ʻana inā e kūkulu ʻia nā ʻōnaehana ma nā ipu a me Kuber a i ʻole?
Hoʻokuʻu ʻia nā hui e hakakā nei no nā nanoseconds mai ke kūkākūkā ʻana. Hoʻonui ka conservatism olakino ma ke ʻano o ka hilinaʻi, akā aia nō nā ʻoihana e noʻonoʻo i nā ala hou.

No kahi hui liʻiliʻi me nā kikowaena ʻelua, ʻaʻohe manaʻo o Kubera, "wahi a Andrey.

Ka loiloi ʻana i ka hoʻohana ʻana o Kubernetes
Ua nīnau ka mea hoʻolohe ʻo Anton Zhbankov i kahi nīnau pahele i ka poʻe apologist Kubernetes: pehea ʻoe i koho ai a hana i kahi noiʻi kūpono? No ke aha ʻo Kubernetes, no ke aha ʻaʻole nā mīkini virtual, no ka laʻana?
